About CNAME records

A CNAME record aliases one hostname to another, so it resolves to wherever the target points. It is common for www and for pointing subdomains at third-party services.

This lookup queries your CNAME (canonical name) records in real time over DNS-over-HTTPS, so you see exactly what resolvers see right now — useful for verifying changes, auditing a setup, or troubleshooting.

FREQUENTLY ASKED QUESTIONS

Got Questions? We Have Answers.

What is a CNAME record?

A CNAME (canonical name) record aliases one hostname to another, so it resolves to wherever the target points. It is common for www and SaaS subdomains.

Can the root domain have a CNAME?

Not per the DNS spec — the apex (example.com) cannot be a CNAME. Providers offer CNAME flattening or ALIAS/ANAME records instead.

Why does my CNAME lookup return nothing?

The name you entered may be an A record rather than an alias, or the subdomain may not exist. Try the exact hostname (for example www.example.com).

How is a CNAME different from a redirect?

A CNAME resolves DNS to another name transparently; a redirect happens at the HTTP layer and changes the visible URL. They serve different purposes.

Is this lookup live?

Yes. CNAME records are resolved in real time over DNS-over-HTTPS.

Does a CNAME affect my SSL certificate?

The certificate must cover the hostname a visitor uses. When you CNAME to a provider, ensure it issues a certificate for your subdomain.
